BERNHARDT oRGENsEN, E BEVERLY, MASSACHU/SETTS, nssronon TO UNITED SHOE MACHINERY CORPORATION, oE rA'rE SON, NEW JERSEY, A CORPORATION or NEW JEEsE LAsrrNe MACHINE" Application filed October 15,1927, Serial No. 226,399. Renewed December 6, 1929.

This invention relates to lasting machines for use in the manufacture of boots and shoes, and is herein illustrated as applied to a machine of thetype disclosed in Letters Patent No. 1,775,225, granted upon an earlier ap-' plication of mine on Sept. 9, 1930, for lasting shoes of that kind in which the upper is fastened to the insole in the lasting operation by cement, for example shoes commonly known as tennis shoes. It is to be understood, however, that the invention is not limited to the lasting of shoes of that particular type nor to a machine organiza tion of that particular character. t

In the lasting of shoes in which the insole is comparatively soft and pliable, such as tennis shoes, it is important to control the insole in such manner that no portion of it will be wrinkled or otherwise displaced by the laying or wiping of the margin of the upper inwardly over it. The present invention, in one of its important aspects, provides novel means for guarding against such displacement of an insole in the lasting operation. In the illustrative application of the invention to means for lasting the toe portion of a shoe by the use of wipers, there are providedmembers for engaging the marginal portion of the insole at the opposite sides of the toe to press the insole upon the bottom of the last, thesemembers comprising rolls which are yieldingly movable in directions away from the bottom face of the insole in response to the inward movement of the wipers, to permit the margin of the upper to be wiped. inwardly between said members and the insole, and are also rotatable to facilitate the inward wiping action of the wipers. As herein illustrated, the rolls are arranged to act also as retarders to increase the effectivewviping pressure of the wipers on the upper by engaging the margin of the upper and bending it outwardly over the edges of the wipers, the rolls being turned by the frictional contact of the upper therewith so that any possibility of undue strain on the upper is avoided. In the organization herein shown, moreover, the insole-controlling rolls are combined with means of the character disclosed in the Letters Pat'- entabove mentioned for controlling the margin of the insole about the end portion of the toe, and with lasting straps arranged to lay the margin of the upper over the insole at the rear side portions of the toe in accordance with the disclosureof other Letters Patent No. 1,778,192, granted upon an application of mine'on Oct. 1a, 1930, the rolls being arranged to operatein the intervals between saidcontroll'i'ng' means and lasting straps. a i

In a further aspect the invention provides novel means for insuring a proper co-ope'rative relation between end-lasting mechanism' and meansfor applying pressure to the bottom of a shoe in any position of adjustment of the lasting mechanism for different sizes of shoes. In machines of the type illustrated the toe-lasting mechanismis mounted for adljustment lengthwise 'ofthe shoe, and in co operation with the lasting mechanism there is provided a presser foot for engaging the toe end of the insole to assist in controlling the insoleand to depress the shoe relativelyto the lasting mechanism; and as applied to such an organization the invention providesconnections for adjusting the presser foot lengthwise of the shoe simultaneously with the toelasting 'mechanism. As. herein illustrated, the presser foot has associated therewith, for simultaneous adjustmentlengthwise of the shoe, means of the character hereinbefore described for also'controlling the marginal portion of the insole, and by the adjustingconnectio ns provided insurance is therefore afforded 'of a proper co-operativerelation between the different insole-controlling devices and the toe end of the insole of each sizeof shoe in accordance with the adjustment of thle toe-lasting mechanism for that size of s 0e. r

The above and other features of the inven tion, including various details of construe: tion and combinations of parts, .willnow be more particularly described by reference to the accompanying drawings and thereafter pointed out in the claims: V

As fully disclosed also in Letters 'atent No. 1,778,192, the side wiper plates 26 are connected at their rear ends to flexible lasting straps 28 through which these plates act to lay portions of the margin of the :upper inwardly over the insole without any substantial wiping action thereon, these straps being arranged to begin their overlaying action on the upper slightly in advance of the inward wiping action of h Pla e 2 in front of h r ps, a lu trated in Fig. 3.

For depressing the shoe relatively to the lasting means and for thereby effecting an up, wiping operation upon the upperaround the t e a d the Pos t oni g of t e e nd. of

. the shoe in proper relation for the wipers 24 26 to wipe the upper inwardly over the insole, as more fully disclosed in the earlier Letters Patent, there is provided mechanism including a toe presser foot 30 which engages the intermediate portion of the toe end of the insole, this presser foot being, adjustably mountedyas (hereinafter described, upon a supporting arm 32 movable lengthwise in a herizenta plane n e holde 34: seemed to a "3. ,whieh i inenhted or er ca move ment and also for turning movement in bearings in the frame of the machine. As disclosed in Letters Patent No. 1,775,225, the post 36 is normally elevated and turned so as'to position the presser foot 30 above and a th rea 10f the e e i n ef the e, and y turning moxzement and downward movement of :thepost in the operation of the machine the presser foot is swung tornwardlyetoa posie011 erer the e ee an i ar d ew wd y he engag the ins le an depres h sh 7 As also disclosed in the earlier Letteli Patent, the machine further provided with means for eontrolliug the margin of (the insole around the .end portien of the toe and @f l'h hfihg-t Wip in Wiping h ma gin of the upper tightly inward over the insole, eempri ing member 38 which gage th insole and acts as a retarder on the upper, This member is curved similarly to the edge of the toe end otthe insole and is supported upon the presser foot-carrying arm 32 by means o-fa-n armetO and linksl2 andAL i. The arm 40 is pivotally connected at l6 to the member :38 to permit this member to adjust itself to the lengthwise contour of the shoe o om he inks e2 and 4e ar pivotally connected to the arm .40 at their lower ends and at their upper ends are pivotally connected respectively to the arm 32 and to a plung r -4 which is m nt d for rtic l movement in the arm 32 against the resistance of a spring 50. A spring 52 connecting h l nk a2 to the arm 2 en s t P s tion he parts as shown in Fig. 1, while permitting the arm 5L0 to be swung by the links a2, {A to carry the member 378 forwardly toward the end of the toe For imparting such forward movement to the member '38 there is connected to the link 4:2, a gear sector 54: tengaged by vertically movable rack bar 56 which is mounted. the arm. 32 with its low er end' projecting downward-1y below the arm, lathe construction herein shown th r is'prov-ided for engagement with an adjustablesclew :57 on the lower end ofthe rack bar 56. a plate ,58 secured to .abracket 6.0 fast nt e fram of the machine. When the arm 82 receives its downward movement t Carry the pres er-foot 0. ntov e gagem nt with th insole and to depress the shoe, the a k ba 55,. by the engagement of the sc ew 57 ith the pla e e5 .,,e u ee the a m 40 and th memb 35 tebeme e .ferwar ly over the t carry he memb .38 near r be he edgeof the insole and nearer to the wiperase that this member is positioned close to the edge'of the insole to hold the margin of the insole upon derstood that the member 38 can'yield bodily upward from the bottom face of the insole against the resistance of the spring 50, and by reason of'the outwardly flared shape of its upper-engaging face itfis thus wedged upwardly by the wipers in the wiping opera tion to permit the margin of the upper to be wiped inwardly between this member and the insole.

The presser foot 30, in the construction herein shown, is pivoted at 62 on a bracket 64 which is vertically adjustable in a guideway formed in the end of the arm 32 to permit a variation of the height of the presser foot relatively to the arm 32 and thus to determine, as desired, the plane in which the bottom face of the toe end of the insole is presented for the action of the wipers. For adjustingthe bracket 64; there is provided an arm 66 con nected to an eccentric 68 mounted in a slot formed in a portion of the bracket 64-, and for maintaining the parts in various positions of adjustment there are provided in the arm 32 a series of holes 7 O arrangedto receive a pin 72 carried by the arm 66.

' The present invention, in its illustrated em-' bodiment, provides means for controlling the marginal portion of the insole at the opposite sides of the toe between the rear end of the member 38 and the lasting straps 28. For this purpose the presser foot member is provided with a pivot stud 74 upon which are pivotally mounted a pair of arms 76 extending outwardly toward the opposite sides of the shoe and each having on its outer end a pair of rolls 78 for engaging the insole near its marginal edge. A spring 80 the opposite ends of which are mounted in sockets formed in the arms 76 tends to swing the rolls downwardly while permitting them to yield upwardly in directions away from the bottom face of the insole. WVhen the parts are in their idle positions, the arms 76 are in engagement with the presser foot 30 to limit downward swinging movement of the rolls, the latter being then so positioned that they extend downward somewhat below the lower face of the presser foot, as illustrated in Fig. 1, so that when the presser foot is carried downwardly into engagement with the insole the rolls will engage the opposite side portions of the insole under spring pressure. The rolls 78 are thus so arranged as to afford additional insurance that portions of the margin of the insole between the member 38 and the lasting straps 28 will not be displaced by the inward wiping action of the wipers 26. As

the wipers continue theirinwardmovement after bending the margin of the upperin wardly over-the extreme outeredge of the in sole, the rolls 78'yield upwardly against the resistance of the spring 80 in response to the wedging action of' the wipers thereon, thus permitting the upper to be wiped inwardlybetween the rolls andthe insole, as will be evident by reference to Fig. 2. It willbe fur ther evident that the rolls 78 act additionally to bend the margin of the upper outwardly over the edges ofthe wipers and thus serve as retarders in the same general manner as the member 38. The provision for turning movement of the rolls 78 'onthe arms 76 in response to frictional engagement of the upper or the wipers therewith facilitates the inward wiping action of the wipers and also avoids any possibility of undue strain on the upper in the locations where the rolls are positioned.

As hereinb'efore described, the toe-lasting mechanism 'includingthe supporting slide 18 is mounted for adjusting movement on the frame of the machine in directions lengthwise] of the shoe to adapt'the machine to operate on shoes of different lengths. For thus ad usting the lasting mechanism there is provlded a screw 82, Fig. 1, which may be operated by a hand-wheel (not shown), as described in Letters Patent No. 1,775,225. As the-toe-lasting' mechanism is thus adjusted for shoes of different lengths, the presser foot 30 and the parts associated therewith, comprising the member 38 and the rolls 78, should also be adjusted in directions lengthwise of the shoe to-operate properly on each size of shoe; The invention further provides means for insuring a proper co-operative relation between the tOelasting mechanism or wipers and the insole-engaging means, without requiring any special attention on the operators part, by connecting the arm 32 to the toe-lasting mechanism so that the arm is adjusted simultaneously with said mechanism through the action of the screw 82. For this purpose there is connected to the slide 18 a rack bar 84 which engages a pinion 86 on a shaft 88 mounted in a stationary bearing on the frame, this shaft being connected at 90 by a universal joint with a member 92 of. a telescopic shaft. The other member 94 0f this telescopic shaft is mountedto slide length- .wise of the member 92 and is connected by a universal joint at 96 to a shaft98 mounted in bearings in the holder 34 on the post 36.

its

Fast on the shaft 98 is a pinion 100 which is I 7 required manner on each size of shoe. It will be evident that by reason of the character of the connections, including the telescopic shaft 92, 94 and the universal joints and 96, the adjustment of the arm 32 is not affected by the vertical movements of the post 36 in the operation of the machine.

The manner of operation of the mechanisms provided by this invention having been :uiiiciently pointed out in connection with the description of these mechanisms, no further explanation is required.
